From the triumphant dream pop of Grimes and the boundary-pushing R&B of Frank Ocean to the tough, frantic British hip-hop of Plan B and the chart-topping country pop of Taylor Swift, PopMatters counts down 2012's 75 best songs.

The Vaccines' latest single is the uber-catchy pop gem "I Always Knew". The video has released well ahead of the 11 November street date. In the UK, the physical single will be backed by "Make You Mine".
